Northern Vietnam Faces Continued Heavy Rains, High Risk of Floods and Potential Storm

Northern Vietnam is bracing for continued heavy rainfall, with forecasters warning of significant risks of flash floods and landslides in the mountainous and midland regions. Over the past month, the north has been hit by four consecutive major rain events. Some mountainous and midland areas have recorded rainfall 15-50% higher than the long-term average.

Weather forecasts for July 12 indicate scattered showers and thunderstorms across northern Vietnam, with rainfall amounts ranging from 10-30 mm, and locally heavier downpours exceeding 70 mm. These rains are expected to be concentrated in the early mornings, afternoons, and evenings. Similar conditions, with moderate to heavy rain, are predicted for Thanh Hoa to Quang Tri in central Vietnam, and scattered showers for the Central Highlands and southern regions.

miền Bắc tiếp tục duy trì mưa rào và giông diện rộng. Trong đó, một số nơi ở miền Bắc có mưa lớn cục bộ với lượng mưa lớn 100 mm.

From July 11 to July 18, northern Vietnam is expected to maintain widespread rain and thunderstorms, with some areas potentially experiencing localized heavy rainfall of up to 100 mm. The situation could escalate significantly between July 19 and July 23, when northern Vietnam may be affected by a tropical convergence band with the potential to form a tropical depression or storm. This would mark the second storm of the season.

During the period of June 11 to July 11, northern Vietnam experienced four major rain spells. The most significant occurred from June 26 to July 6, influenced by a tropical convergence zone and the remnants of the first storm, resulting in widespread heavy rain. Some areas, like Quang Ninh province, saw total rainfall between 300-500 mm, with Mong Cai recording an exceptional 817.7 mm. Central Vietnam also saw two rain events in June and July, while the south-central coast experienced three.

Đặc biệt, từ ngày 19.7 - 23.7, miền Bắc đón đợt mưa lớn diện rộng. Theo tính toán của Trung tâm Dự báo khí tượng thủy văn quốc gia, trong thời gian này, miền Bắc có khả năng chịu ảnh hưởng của một dải hội tụ nhiệt đới có nguy cơ hình thành xoáy thuận nhiệt đới (bão hoặc áp thấp nhiệt đới), gây ra một đợt mưa lớn diện rộng. Nếu như xoáy thuận nhiệt đới này phát triển, mạnh lên thành bão, đây sẽ là cơn bão số 2 trong năm nay.
